The Gastro-Intestinal Microbiota in Haematology.

Acta Haematol
Background: The gastro-intestinal microbiota is a key regulator of systemic immunity and inflammatory tone and it contributes to normal haematopoiesis through microbial metabolites, barrier integrity, and host-microbe immune signalling. Disruption of this has been increasingly linked to the development, clinical course, and treatment-related ...

Role of the Spore Coat Proteins CotA and CotB, and the Spore Surface Protein CDIF630_02480, on the Surface Distribution of Exosporium Proteins in Clostridioides difficile 630 Spores

Microorganisms, 2022
Clostridioides difficile is Gram-positive spore-former bacterium and the leading cause of nosocomial antibiotic-associated diarrhea. During disease, C. difficile forms metabolically dormant spores that persist in the host and contribute to recurrence of ...

Respiratory Heme A-Containing Oxidases Originated in the Ancestors of Iron-Oxidizing Bacteria

Frontiers in Microbiology, 2021
Respiration is a major trait shaping the biology of many environments. Cytochrome oxidase containing heme A (COX) is a common terminal oxidase in aerobic bacteria and is the only one in mammalian mitochondria. The synthesis of heme A is catalyzed by heme

Characterization of Exosporium Layer Variability of Clostridioides difficile Spores in the Epidemically Relevant Strain R20291

Frontiers in Microbiology, 2020
Clostridioides difficile is a Gram-positive anaerobic intestinal pathogenic bacterium and the causative agent of antibiotic-associated diarrhea. C. difficile spore is a dormant state which acts as a vehicle of transmission and infection. In C.

The chaperone ClpC participates in sporulation, motility, biofilm, and toxin production of Clostridioides difficile

Journal of Global Antimicrobial Resistance, 2023
: Objectives: Clostridioides difficile is a nosocomial pathogen that is associated with the use of antibiotics. One of the most worrying aspects of C. difficile infection is its ability to resist antimicrobial therapies, owing to spore formation.
